To select an appropriate location for well installation, and to decide on its construction, materials, operational regime, and the necessity for additional infrastructure such as drains, a comprehensive assessment of water quality at the site of interest is imperative. Moreover, forecasting the water quality under the anticipated operational conditions of the well holds even greater significance. Water quality assessment including calcium saturation provides insights into the mineral content of groundwater, which is essential for assessing water quality and optimizing treatment processes. By understanding calcium saturation levels, appropriate corrosion control measures can be implemented to mitigate these risks. Excessive calcium saturation and scale formation can impact aquatic ecosystems by altering water chemistry and habitat conditions. Overall, understanding calcium saturation in groundwater is very important for maintaining water quality, preventing infrastructure corrosion, minimizing environmental impacts, and optimizing water treatment processes. Subsequently, this discussion delves into an analysis of the findings derived from water quality testing conducted at eight observation piezometers. With the aim of assessing the corrosivity of water and its potential to form calcium carbonate scale the Langelier Saturation Index and Ryznar Stability Index were calculated. info:eu-repo/semantics/conferenceProceedings Langelier Saturation Index, Ryznar Stability Index. application/pdf 1359890 bytes 31st International conference Ecological Truth & Environmental Research EcoTER'24, 18-21 June 2024, Sokobanja, Serbia str. 89-94 http://creativecommons.org/licenses/by-nc-nd/4.0/legalcode eng https://unilib.phaidrabg.rs/o:4926 ISBN: 978-86-6305-152-2 Obradović, Vesna Lekić, Jelena Perović, Marija Evaluation of Corrosion Potential Using Physicochemical Water Quality Assessment University of Belgrade, Technical Faculty in Bor 2024
